Description
The total number of good packets received that were directed to the broadcast
address. This does not include multicast packets.
The total number of inbound packets that contained errors preventing them
from being deliverable to a higher-layer protocol.
The total number of packets received that were longer than 1518 octets
(excluding framing bits, but including FCS octets), and had either a bad Frame
Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad
FCS with a non-integral number of octets (Alignment Error). This definition of
jabber is different than the definition in IEEE 802.3 section 8.2.1.5 (10BASE5)
and section 10.3.1.4 (10BASE2). These documents define jabber as the
condition where any packet exceeds 20 ms. The allowed range to detect
jabber is between 20 ms and 150 ms.
The total number of packets received that were less than 64 octets in length
with ERROR CRC (excluding framing bits but including FCS octets).
The total number of packets received that were less than 64 octets in length
with GOOD CRC (excluding framing bits but including FCS octets).
The total number of packets received that had a length (excluding framing bits,
but including FCS octets) of between 64 and 1518 octets, inclusive, but had a
bad Frame Check Sequence (FCS) with a non-integral number of octets.
The total number of packets received that had a length (excluding framing bits,
but including FCS octets) of between 64 and 1518 octets, inclusive, but had a
bad Frame Check Sequence (FCS) with an integral number of octets
The total number of frames discarded as this port was overloaded with
incoming packets, and could not keep up with the inflow.
A count of valid frames received which were discarded (i.e., filtered) by the
forwarding process.
The total number of frames dropped in the forwarding process because the
destination address was located off of this port.
A count of MAC Control frames received on this interface with an opcode
indicating the PAUSE operation. This counter does not increment when the
interface is operating in half-duplex mode.
The number of frames discarded from this port due to being an unacceptable
frame type.
The number of frames discarded when a lookup in the multicast tree for a
VLAN occurs while that tree is being modified.
address and are not supported by the system.
The number of frames discarded that are destined for FF:FF:FF:FF:FF:FF
when Broadcast Storm Recovery is enabled.
The number of frames discarded that have CFI bit set and the addresses in
RIF are in non-canonical format.
